INSTRUMENT FOR APPLYING LIQUID FINISH TO SHOES.

Specification of Letters Patent.

Patented Feb. 19, 1918.

Application filed October 16, 1917. Serial No. 196,953.

To all whom it may concern.

Be it known that I, HENRI Manors, a citizen of the United States, residing at Lewiston, in the county of Androscoggin and State of Maine, have invented certain new and useful Improvements in Instruments for Applying Liquid Finish to Shoes, of which the following is a specification.

My invention relates to improvements in instruments for applying liquid material, paint or blacking for instance, to the welt or sole edge of a boot or shoe. This invention relates specially to improvements upon the invention set out and described in my pending application, Serial No. 168,350.

In the drawings herewith accompanying and forming a part of this application Figure 1 is an elevation partly in section of my device, showing it adapted to operate on the welt; Fig. 2 is a detail elevation of a portion of the same looking from the right side; Fig. 3 is a transverse sectional view of Fig. 1, taken on line zc.r, and Fig. 41 is a sectional view of the nozzle.

The same reference characters indicate like parts in the several figures.

In said drawings 1 is a container and 2 a closure therefor. Inserted in the container, preferably through the top is a pipe (3, the nozzle end of which for convenience is curved as seen at 7. In the end of the nozzle is inserted a brush 8 which has one or more discharge openings 9 therein. At a convenient point in the pipe is a stop 10 having a longitudinal opening 11 therein. Extending transversely through the pipe and stop is a reciprocating valve 12 provided with an opening 13. The valve is held by a spring 11 normally in position so that opening 13 is out of register with opening 11. I have shown a flat spring having one end attached to a fixture 15 mounted on the pipe and the flat end bifurcated as seen at 16 to loosely engage the valve stem. The spring is held in place by an adjusting nut 17, by means of which the valve can be adjusted so that, if desired, any predetermined portion of open ing 13 can be made to register with opening 11. Pivotally attached to pipe 6 or to the fixture 15 mounted thereon is a lever 18, the upper end 19 of which is bifurcated to slidingly engage the stem of valve 12 and the lower end of which terminates in a handhold 20. Slidably mounted on pipe 6 is a sleeve 21 which may be locked thereto by means of a set-screw 22. The sleeve supports an arm 23 to which is secured in any convenient manner a guide carrier 24 carrying a guide 25 which may be of any suitable form or shape adapted to engage some part of the shoe and positioned relative to the brush or brushes so that the finish may be applied to any desired part or parts of the shoe as the device is moved relative to the shoe. I have shown in Fig. 1 a guide adapted to be used when the finish is being applied to the welt. It is. preferably mounted on a yielding spring 26 secured to a plunger 27 yieldingly mounted in the carrier and adapted to be held fixedly in any desired position by means of a threaded nut 28.

The foregoing has reference to the in vention set out and described in said pending application. I have found it important to combine therewith an air pump operated simultaneously with and by means of the feed valve operating lever.

I have shown a pump 29 and its plunger 30 and a convenient method of connecting up the plunger with said lever 18. To the pump barrel I attach a bracket 31 on which is pivotally mounted an arm 32, its lower end terminating in a pinion 33. Supported by the pump barrel also is a guide pipe 31, and adapted to reciprocate in said guide pipe is an angular rod 35 having an offset by which the plunger and the plunger rod 36 is lifted. Connecting arm 32 with said offset is a coil spring 37, the tension of which tends constantly to raise the plunger. The plunger is lowered by a rack bar 38 adapted to reciprocate in a sleeve 39 and to engage said pinion 33. The rack bar is operated by lever 18 to which it is secured by a link 40 and to the bar by means of a pin 11 passing through a slit 12 in the sleeve. The pinion bar also carries a push rod 45 pivotally attached thereto and having the upper end 46 adapted to slide freely in the offset portion of the rod 35 when the plunger is lowered. When the plunger is lowered the spring is expanded due to the resistance of the plunger in the pump and when the lever is released the spring contracts and lifts the end of the pinion bar and by means of the push bar raises the plunger. If the plunger is lowered too quickly it gives too much air pressure in the container and carries too great a flow of the finishing material. But this is regulated by the spring yielding to permit the push bar to descend without the plunger. Connected to the bottom of the pump is a pipe 43 which terminates in said container and is provided with a check valve 44.

The form and construction of many of the parts which go to make up this device may be varied and still. be within the spirit and scope of my invention.

I claim:

. 1. In a device of the character described, a liquid container, a feed pipe entering the container, a brush in said pipe, a guide adjacent said brush adapted to be moved manually in contact with some part of the Work, a valve in said pipe, means for operating said valve and an air pump operable by the valve operating means for supplying air under pressure to said container.

2. In a device of the character described, a liquid container, a feed pipe entering the Copies of this patent may be obtained for five cents each. by addressing the Commissioner of Patents.

container, a brush in said pipe, a guide ad jacent said brush adapted to be moved manually in contact with some part of the work, a valve in saidpipe, a lever for operating said valve and an air pump operable by the valve operating means for supplying air under pressure to said container. V I .3. In adevice of the character described, a liquid container, a feed pipe entering the container, a brush in said pipe, a guide ads jacent said brush adapted to be moved man ually in contact with some part of the Work, a valve in said pipe, a lever adapted to operate said valve and an air pump'operable by the valve operating means through inter? mediate mechanism for supplying air under pressure to the container.

In testimony whereof I afiix my signature.
